There is a critical need to develop interventions to reduce barriers to optimal asthma management and reduce the significant risk for asthma-related morbidity experienced by minority children, especially African- American adolescents with poorly controlled asthma. There are few clinical trials focusing on African-American adolescents with poorly controlled asthma, and intervention studies targeting African-American adolescents with asthma in general or African-American children with poorly controlled asthma in particular are characterized by methodological limitations and/or limited effects on objective health outcomes. Multisystemic Therapy-Health Care (MST-HC) is an intensive, multi-component, home-based psychotherapy that targets the multiple causes of poor adolescent asthma management across individual, family and community systems. In a randomized clinical trial, we showed that MST-HC was significantly more effective than home-based family support in improving adherence to controller medications and improving lung functioning among African- American adolescents with moderate to severe, poorly controlled asthma up to six months after the completion of the intervention. In addition, MST-HC reduced asthma-related hospitalizations and associated ED visits. The primary purpose of the proposed study is to adapt MST-HC for use in real world, public healthcare settings and test it in a T3 translational trial. The new intervention, Reach for Control (RFC), will be housed in a pediatric emergency department (ED) at Children's Hospital of Michigan (CHM)and will be adapted for delivery by community health workers (CHWs). The design is an effectiveness-implementation ?Hybrid 1? design where the primary aims are to determine the effectiveness of an evidence-based intervention in a real-world setting, and the secondary aims are to gather information about the context for implementation and barriers/ facilitators to implementation. For our effectiveness aim, we will conduct a randomized effectiveness trial with 170 high risk adolescents with poorly controlled asthma seen in the ED for an asthma exacerbation. RFC will be delivered by Wayne Children's Healthcare Access Program, a community agency providing health care services to underserved children in the Detroit area and will be compared to the agency's standard care intervention for youth with poorly controlled asthma. For our implementation aims, we will evaluate the effectiveness of identification, screening and referral to RFC by ED clinical staff via a clinical pathway. We will study barriers and facilitators to the implementation of RFC (both its integration within the ED and delivery by CHWs) using a mixed methods approach. We will also develop and evaluate an efficient and effective method of measuring CHW fidelity to RFC and conduct a cost analysis that will inform decisions such as treatment dose and CHW caseload in future real-world implementations. If successful, the study has the potential to improve quality of life for a vulnerable population while reducing healthcare costs.
There is a critical need to develop and disseminate successful illness management interventions for African American adolescents with poorly controlled asthma. The purpose of the proposed study is to adapt and test an evidence-based intervention for these adolescents for use in real world, pediatric emergency departments (EDs) and evaluate factors affecting intervention implementation. If successful, the study has the potential to improve quality of life for a vulnerable population while reducing healthcare costs.
